1) the progress callback gets called more frequently (at times)
  2) libcurl *might* call the callback when it receives a signal

appropriate test case to use it.  For now, this is treated the same as the
"SSL" feature because curl doesn't list it separately.

  machine type too.

  upload a file it couldn't open. Bug #1676581
  (http://curl.haxx.se/bug/view.cgi?id=1676581)

test, fixing KNOWN_BUGS #11.  Fixed some tests to more accurately specify
their required servers and features.

libtool to skip C++ and Fortran checks in patchset:
http://cool.haxx.se/cvs.cgi/curl/ares/configure.ac.diff?r1=1.60&r2=1.64

supports only ftps:// URLs with --ftp-ssl-control specified, which
implicitly encrypts the control channel but not the data channels.  That
allows stunnel to be used with an unmodified ftp server in exactly the
same way that the test https server is set up.
Added test case 400 as a basic FTPS test.

unencrypted data connections.

it fails if the macro that is being undefined is not already defined. To
make this work under all cases and be sure that at a certain point some
specific macro isn't defined we must use the following style in configure:

m4_ifdef([macro], [m4_undefine([macro])])

Luckily, they weren't needed.

  makefiles that are included in the source release archives, generated from
  the Makefile.vc6 files by the maketgz script. I also modified the root
  Makefile to have a VC variable that defaults to vc6 but can be overridden to
  allow it to be used for vc8 as well. Like this:

    nmake VC=vc8 vc

tearing down the test ftp server due to a read error condition.

in builds with HTTP support disabled to keep consistent enum values
for CURLMstate in all kind of builds.

line break detection in daily build logs.

  server through a proxy and have the remote https server port set using the
  CURLOPT_PORT option, protocol gets reset to http from https after the first
  request.

  User defined URL was modified internally by libcurl and subsequent reuse of
  the easy handle may lead to connection using a different protocol (if not
  originally http).

  I found that libcurl hardcoded the protocol to "http" when it tries to
  regenerate the URL if CURLOPT_PORT is set. I tried to fix the problem as
  follows and it's working fine so far

Added -DHAVE_STRUCT_TIMEVAL to CFLAGS.

config.h includes ../lib/config.dos.

Simplified dependency generation.
